Abstract

The article shows that when analyzing the physical and mechanical processes of drying the flotation concentrate for the automation of the control of the drum drying furnace, it is important to take into account a number of features of the enrichment of non-ferrous metal ores, since non-ferrous metal ores are very diverse in their composition and properties. It is noted that based on the physical and mechanical properties of ores and in connection with their complex composition, small and fine dissemination of valuable components in non-ferrous metal ores, the main method of enriching these ores is flotation. The methods and materials of the article are based on the completed project for the construction of a pilot plant for filtration, drying and roasting of the product at a mining and metallurgical plant. The automation system under consideration uses modern technologies and high-performance equipment that fully meets not only the physical and mechanical processes of drying the flotation concentrate, but also all the necessary functional requirements. The presented results and discussion of the features of automation and control of the process of drying flotation concentrate in a drum drying oven take into account both current and future research needs and opportunities.
